A crypto exchange based in Hong Kong, CoinEx, is dealing with a security breach. They've lost a significant amount of ETH and TRON from their hot wallets (4,946 ETH and 354,762 TRX so far). The company is looking into it and has promised to reimburse affected users.
I know nothing about the exchange, but as we can see, that’s one of the reasons why we shouldn’t leave our coin on the exchange. Anything can happen to any exchange at any particular time, so leaving our coin there is really risky and dangerous. The exchange might not be popular, but even popular exchanges with good reputations and security are being hacked, so to be on the safer side, just get a non-custodial wallet and store your coin there. If the wallet is properly secured, then nothing will be wrong with your coin, and you will have total control of your coin, not that anyone will be controlling your coin.
